I have had my Concealed Carry Permit for a couple years. I was in Law Enforcement for 17 years before that, and did not need one.
I carry several different handguns, just because I can. What I carry can be decided by the weather out, where I am going, or by what I might decide to wear.
In cooler weather when I am wearing a jacket, vest or coat that I may have to take off. I normally carry my 638 in an inside pocket on my cover garment. I keep the vest, jacket, etc with me when I have to remove it.
Summer I have gotten into the habit of buying my shirts in Tall to get a little more length. I like to carry my 638, 310 Night Guard, and 625 in 3" under an untucked shirt. Nylon Fishing shirts work well in hot weather. My favorite carry option for warm weather.
A hair cooler and I will go with a 1 size to large shirt with long tail worn like a jacket. This will work with my 4" 64, my 4" 610, and 1911.
I like Lobo's Pancake holsters for my revolvers. I mostly carry my 1911 in a Rafter S (Black Shark Skin) Askins Avenger style holster. I carry everything at app the 4 O'Clock position.
I shoot all of my carry guns in our monthly Defensive Pistol Match. Some times I will shoot 2 of them, some times I might shoot 4 or 5 different guns if we have a lite turnout. I use my carry holsters to shoot the matches. The monthly pistol match is my practice. I might shoot at other times, but I make the pistol match every month.
My 2 most carried handguns (Town Carry) at this time would be my 638 and my 310 Night Guard. The N Frame Airweight is no problem to carry at all.
Running around on my ATV or UTV over at a buddies, etc I am likely to be carrying my 4" Model 64. This is my main SSR match pistol, and I like it for bumming around carry. Right now I have it full of HP ammo. In the Summer it is likely to be loaded with 2 shotshells, and 4 semi wadcutters. Most of my gun fights are with poison snakes.
I do not subscribe to only shooting one gun for ccw, and shooting it well. A while back I shot 5 guns in one day in a match. I beat my 1911 CDP score with my 64 in SSR. My total point spread was around 10 points between all 5 guns. If I had brought out my XDm 40 I doubt that the results would have been any different on the score spread.
If for some reason I might be at a threat level higher than my normal Green. I would be carrying my 1911, or my 310.
Just my 2 cents
